An assembling method for a multi-core cable having a plurality of electrical insulated wires is designed to connect one-end-portions of the electrical insulated wires to electrode patterns, respectively, of one circuit board, correspondingly connect other-end-portions of the electrical insulated wires to electrode patterns, respectively, of the other circuit board, compute intersection coefficients on one end side and the other of the cable, and iterate interchanging connecting destinations for the one-end-portions of the electrical insulated wires, correspondingly interchanging connecting destinations for the other-end-portions of the electrical insulated wires, and computing the intersection coefficients on the one end side and the other of the cable. The connecting destinations for the electrical insulated wires to the electrode patterns are determined in such a manner that a maximum intersection coefficient denoting either larger one of the respective intersection coefficients of the one end side and the other of the cable is made small.

A solder with ground bar includes a first unit and a second unit. The first unit includes a first ground bar and a first solder layer attached to one side of the first ground bar. The second unit includes a second ground bar and a second solder layer attached to one side of the second ground bar. The first unit and the second unit are arranged in such a manner that the first solder layer and the second solder layer face each other. The first solder layer and the second solder layer are partially joined together.

A communication light detection adapter includes an adapter main body in which a light extraction hole is formed, a sliding lid attached to the adapter main body so as to slide between a closed position to close the light extraction hole and an open position to open the light extraction hole, and an energizing member to apply a pressure to the sliding lid in a direction from the open position toward the closed position.
